Determining the spin of supersymmetric particles at the LHC using lepton charge asymmetry.
Barr, Alan (HEP, Cavendish Laboratory, University of Cambridge, 200405)If signals suggesting supersymmetry (SUSY) are discovered at the LHC then it will be vital to measure the spins of the new particles to demonstrate that they are indeed the predicted superpartners. A method is discussed ... 
Discovering anomaly mediated supersymmetry at the LHC.
Barr, Alan; Lester, Christopher G.; Parker, Michael A.; Allanach, B. C.; Richardson, P. (HEP, Cavendish Laboratory, University of Cambridge, 200208)The discovery potential of the LHC is investigated for the minimal anomalymediated supersymmetry breaking (mAMSB) scenario, using the ATLAS fast detector simulator, including track reconstruction and particle ... 
Discovering anomalymediated supersymmetry at the LHC
Barr, Alan; Lester, Christopher G.; Parker, Michael A.; Allanach, B. C.; Richardson, P. (Journal of High Energy Physics, 200304) 
Extracting the flavor structure of a baryon number Rparity violating coupling at the LHC.
Allanach, B. C.; Barr, Alan; Parker, Michael A.; Richardson, P.; Webber, Bryan R. (HEP, Cavendish Laboratory, University of Cambridge, 200106)The detection of the flavour content of jets produced from Rparity violating neutralino decays is investigated in the case where one baryonnumber violating coupling dominates. Simulations are performed of the ATLAS ... 
m(T2): The Truth behind the glamour.
Barr, Alan; Lester, Christopher G.; Stephens, Phil (HEP, Cavendish Laboratory, University of Cambridge, 200304)We present the kinematic variable, mT2, which is in some ways similar to the more familiar ‘transversemass’, but which can be used in events where two or more particles have escaped detection. We define this variable ... 
Measuring supersymmetric particle masses at the LHC in scenarios with baryon number Rparity violating couplings.
Allanach, B. C.; Barr, Alan; Drage, L.; Morgan, D.; Parker, Michael A.; Webber, Bryan R.; Richardson, P. (Journal of High Energy Physics, 200104) 
Measuring supersymmetric particle masses at the LHC in scenarios with baryon number Rparity violating couplings.
Allanach, B. C.; Barr, Alan; Drage, L.; Lester, Christopher G.; Morgan, D.; Parker, Michael A.; Webber, Bryan R.Richardson, P. et al. (HEP, Cavendish Laboratory, University of Cambridge, 200102)The measurement of sparticle masses in the Minimal Supersymmetric Standard Model at the LHC is analysed, in the scenario where the lightest neutralino, the ˜χ01 , decays into three quarks. Such decays, occurring through ...
